Electricity in September 2024: Demand Up 4.2% on September 2023

Demand in the 86 countries with data for both September 2024 and September 2023 was 2,311 TWh in September 2024, up 4.2% on September 2023. Those 86 countries cover 92% of world electricity demand (measured on 2025 demand), so this is a review of the reporting countries, not a world total. Low carbon sources supplied 41.6% of their generation in September 2024.

How This Month Is Measured

  • Coverage. 86 countries reported September 2024. 86 of them also have September 2023, and those 86 are the like for like set behind every figure above. Together they made up 92% of world demand in 2025. A month is published only when at least 10 countries and 60% of world demand are covered.
  • Not a world total. These sums cover the reporting countries only.
  • Carbon intensity. The figure for the group weights each country's monthly intensity by its generation; country rankings use Ember's own monthly intensity.
